BAIR, OF HANOVER,` PENNSYLVANIA FLOORcoNsTnUeTIoN Application led September 15,*:5193Li SerialfNo. 552,944:

The present invention relates to a tloor construction for buildings andhas for some of its objects to provide, in a manner as hereinafter vsetforth, a iioor which will be strong, durcome apparent from a study ofthe following y specification, taken in connection with the companyingdrawings wherein like characters of reference designate correspondingparts throughout the several views, and wherein y Figure l is a top planview showing an emboflim ent of a floor constructed in accordance withthe present invention.

Figure 2 is a. view in vertical section taken substantially on the line2-2 of Figure vl.

Figure 3 is a detaill view in perspective showing a pair of blocks whichconstitute the important elements of the invention.

Figure 4 is a view in top plan showing a modification of the invention.

Figure 5 is a vertical sectional view taken substantially o-n the line 55 of Figure 4.

Figure 6 is a vert-ical sectional view taken substantially on the line6-6 of Figure 4.

Referring now to thedrawings in detail,

it will be seen that the reference numeral l blocks communicate. Thepairs of blocks,y

as seen in Figure 1 of the drawings, are arranged in spaced,`parallelrows on suitable forms and reinforcing bars 5 are arranged between therows. l/Vhen arranging the blocks in the rows 'the comparatively thickwalls 3 of certain of the pairs are disposed uppermost and thecomparatively thick walls 3 of theother pairs are disposed lower-` mostas illustrated to advantage in Figure Q ftlie drawings. This is for theypurpose 'effftaking care ofl compression and. tension.

inthe completed"ioor,`

\ Conereteor other-suitable*material is then poured between `the pairsoffbl'ocks. to form the joints `6 and the supporting beams 7.Thefjoi'nts: 6 are'flush-with fthe upper and.- lower surfaces ofthefblocks 1,*it being. un necessary to provide La layer fof concreteeither above orbelow the blocks. This constitutes ya most importanti anddesirable feature vof-theiin'vention. Y l

In the modified form of the rinvention illustratedf inV Figures 4,5.and6 of. the drawings; adjacentf'pairsnf theblocks are disposed at rightangles. The opposed edges of the comparatively thick walls 8 of thepairs of blocks are formed with recesses which, in

. conjunction with each other, define channels or grooves 8 for thereception of the concrete or other joint forming material, as indicatedat 9. In other respects, the modified form of the invention issubstantially the same as the forni shown in Figures l to 3, inclusive',of the drawings.' k

The pairs of blocks may be arranged in any desired manner in the floorother than as shown in the drawings. For example, the pairs of blocksmaybe arranged diagonally with respect to each other. It may be well tohere invite attention to the fact that the channels 8 in Figures 4 to 6,inclusive, of the drawings also extend on vertical sides or ends of thepairs of blocks.

t is believed that the many advantages .of a floor constructed inaccordance with the present invention will be readily understood, andalthough the preferred embodiments of the vinvention are as illustratedand described, it is to be understood that further modifications may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is l. A yfloor construction comprising pairs ofsubstantially hollow, coinplemental blocks, said blocks being open onone side and closed on the other sides, the open sides of the pairs oftheblocks being disposed in abutting engagement with each other, saidblocks including comparatively thin and thick horizon- Y tal Walls, anda joint of suitable material connecting the pairs of blocks together,certain of the opposed edges of the pairs of 5 blocks having opposedrecesses therein deiining, in conjunction With each other, channels forthe reception of the joint material. 2. A floor construction comprisingpairs of substantially hollow, complemental blocks, said blocks beingopen onone side and closed Y on theirother sides, the pairs of blockshaving their open sides in abutting engagement With each other, saidpairs of blocks being spaced `from each other-,said pairs of blocks l5including comparatively thin andthick horizontai walls, thecomparatively thick hori-` Zontal Walls of certain of the pairs ofblocks being disposed uppermost, the comparatively Y thick horizontalWalls of the other pairs of 29 blocks being disposed loyverlnost,Vreinforcing rods extending between thek pairs of blocks, and acementitious joint disposed between the pairs of blocks for connectingsaid pairs together, certain of the abutting edges Y of the pairs ofblocks having recesses therein deiining, in conjunction With eachother,channels for therreception of the joint material.

In testimony whereof I affix my signature. 30 v j Y GEORGE L. BAIE.
